The goal ofgraph4lg is to make easier the constructionand analysis of genetic and landscape graphs in landscape geneticsstudies (hence the namegraph4lg). The package allows toweight the links and to prune the graphs by several ways. To ourknowledge, it is the first software which enables to create geneticgraphs with such a large variety of parameters. Besides, it allows tocarry out preliminary analyses of the spatial pattern of geneticdifferentiation in order to choose the best genetic distance and pruningmethod in every context. Lastly, it makes possible the comparison of twospatial graphs sharing the same nodes.
You can install the released version of graph4lg fromCRAN with:
